Universal filtered multi carrier (UFMC) system is considered to be the best choice for 5G waveform when compared with orthogonal frequency division multiplexing (OFDM), filtered OFDM (f-OFDM), filter bank multi carrier (FBMC) and generalized FDM (GFDM) in terms of spectral leakage, complexity and compatibility with 5G. The all multi carrier systems are suffers from high peak to average power ratio (PAPR) causes non linear functioning in receiver. In this paper, we proposed a Hirschman optimal transform (HOT) based pre-coding for reducing the PAPR in UFMC systems. Results reveals that HOT pre-coded UFMC promising less PAPR compared with discrete cosine transform (DCT), discrete Hartley transform (DHT) and discrete sine transform (DST) and discrete Fourier transform (DFT).
